The power unit, main components of the transmission system, rotation mechanism, auxiliary equipment, and cab of a common full-revolution hydraulic excavator are all installed on a rotatable platform, commonly referred to as the upper turntable. Therefore, a single-bucket hydraulic excavator can be summarized as three parts: the working device, the upper turntable, and the travel mechanism. The transmission system of a single-bucket hydraulic excavator transmits the power output from the diesel engine to the working device, rotation device, and travel mechanism.There are many types of hydraulic transmission systems for single-bucket hydraulic excavators. Conventionally, they are classified based on the number of main pumps, the adjustment method of power, and the number of circuits. There are six categories: single-pump or dual-pump single-circuit fixed displacement system, dual-pump dual-circuit fixed displacement system, multiple-pump multiple-circuit fixed displacement system, dual-pump dual-circuit variable displacement with power adjustment, dual-pump dual-circuit full-power variable displacement system, and multiple-pump multiple-circuit mixed fixed or variable displacement systems. Based on the oil circulation method, they are divided into open system and closed system. According to the oil supply method, they are categorized as series system and parallel system.

 

Experimental objectives: 1. Combined boom 2. Changes in air pressure transmission
Experimental Cognition:
Wooden Frame: Overall Support Structure for Rolling Balls
Sippy cup: Fixing rope
Experimental procedures:
1. Experimental preparation: Identify experimental equipment: wooden frame, straws.

Experiment Report:
The advantage of the integral boom is its simple structure, light weight, and high stiffness. The disadvantage is that there are few available working devices for replacement, resulting in poor versatility, and it is mostly used on excavators with similar long-term operating conditions. The integral boom can be further divided into two types: straight booms and curved booms. The straight booms have a simple structure, light weight, and easy manufacturing, and are primarily used in suspended excavators. However, they cannot achieve a large digging depth like those of general-purpose excavators; the curved booms are the most widely used structural form currently. Compared to the straight booms used by other manufacturers, they allow the excavator to reach a greater digging depth, but reduce the soil unloading height, which meets the requirements for the backhoe operation of excavators.
